BOX .AND METHOD or MAKING THE sum.

7 Application filed February 2, 1922, Serial No. 533,624. Renewed August5, 1924.

The present'invention is an improvement upon the method and boxstructure disclo2sed in my Patent No. 1,408,4t7 9, March 7, 19 2.

According to that disclosure blank as- I semblies are produced by what Ihave described as a, continuous method, or in some cases they may beotherwise produced, and these blank assemblies are so formed that whenthey are folded into box shape and properly secured they present a.close approximation in appearance to the highest class of covered boxes,the inner 'peripheral margins of the shellwalls being covered by anoverlapped marginal portion of the cover sheet, and all exposed wallsand edges of the shell material being concealed by the cover paper, withthe exception of certain edges of the shell end wings which are leftmore or less exposed. V

While boxes having the described characteristics are suitable for manypurposes, the presence of exposed shell edges renders them undesirablein cases where the highest possible finish is desired. The object of thepresent invention is to provide modifications and improvements in theabove mentioned method and structure, so that boxes previous structuremay be produced, but

- with the important difference that the shell end wing edges as well asall other exposed surfaces and edges of the shell material are overlaidand concealed by the cover blank.- The present improvements are alsodevised so that the boxes may be produced when desired, by a continuousproduction method generally conforming to the method disclosed in theabove identified application, with improvements for the presentpurposes, as sufficiently described hereafter.

The accompanying drawings show certain exemplifying embodiments Oftheinvention. After considering these persons versed in the art willunderstandthat many modifications may be made within the principles ofthe invention, and I contemplate the employment of any method ofproduction and structures which are properly within the scope of theappended claims.

In the drawings:- I Fig. 1 is a perspective and largely diagrammaticview, explanatory of the continuous production method.

Fig. 13 is a similar view of a'box made from an assembly like Fig. 11.

In accordance with the'continuous assembly method (Fig. 1) a continuousstri of shell material W, usually card boar of suitable grade andthickness, is advanced from a suitable source of supply, such as a roll(not shown) and during its advance at a suitable point is provided withlongitudinal creases or score marks 12. At a suitable point in theadvance of the shell strip, apertures are punched in it by suitablecutting or punching devices, and this punchin as may ota may be done inone or two stages. e convenient, the punchlng operations, howeverperformed, resulting in the formation of major transverse openings a, ofsubstantially rectanguar form. Rectangular enlargements b of theseopenings are also provided, resulting in the resent specific embodimentin a substantial y H -shaped Opening of which the margins c are usuallysubstantially in line with the longitudinal score'marks 12. These.apertures define the I shape .of the shell end wings when the blankassembly is completed. I

At a suitable point in theadvance of the shell strip it is brought intoassociation with a continuous strip of cover material X which,

may beadvanced from a roll B andis ad hesively conditioned Onthe surfacewhich is to erigagethe shell material, a glue roll 5 being shown toexemplify means for applying adhesive to the cover strip. The

cover strip is brought in contact with they 1. The apertures of theshell leave exposed the adhesively coated cover material, readyforsubsequent box forming operations.

Successive portions of the continuous assembly are .then severed alongthe transverse individual blank assemlines 15, producin imilarassemblies may-be blies A, Fig. 2.

also produced by association of properly formed shell and cover blanksassufliciently explained in the reviously identified application. The inividual blank assem 1y,

however produced, in the present representative form, comprises a pieceof shell material including a body portion 20, side wings 21', cornerlaps 23 extending from the ends of the side. wings, and end wings 22.The outer or under'face of the shell is covered by the cover materialwhich includes portions corresponding generally to the parts of theshell blank above described,

and identified by the same'reference characters with the addition of aprime mark. Margins a: of the cover are-turned over and secured to innermarginal portions of the shell along the outer edges-of the side wingsand corner laps. The'shelllend-wings are soformed that a stripor margin1 portion of the cover end wing 22 extends beyond.

theshell end wing about all of its free sides,

and this marginal portion of the cover ma terial is provided withadhesive which may have been applied during the continuous assemblyoperations as above described, or

- may be otherwise applied inidifierent ass'embly methods. The sidemargins 26 of the shell end-wings are located inward considerably fromthe adjacent edges of the cover end wings, for reasons later'described.

a suitable point in the box-,'formation operations, and in some casesbefore the individual blank assemblies are severed from the continuousassembly, cuts are made along the lines 24, severing the cover materialalong hnes corresponding to the inner Ion-- gitudinal hues of the shellcorner laps '23.-

In oneway of forming the cuts 24, they I may be made' at;the same timethat the transverse severing cuts '15 .are'made,

s ntably formed cutter or knife. j The assemblyis now folded up into,box

manner corner laps at a suitable point in the assembly operations areprovided with adhesive 25, and this application may be made while theblank assembly is still in flat form, as shown in Fig. 3, or at anyconvenient later stage up to the time of lip-folding the assembly endwings.

Fig. 6 shows the assembly end wings folded up against the corner laps,the shell end wings 22 being pressed against the adhesive surfaces 25.The material of the cover end wings 22' extends beyond all the edges ofthe shell and the outer marginal portions of the cover end wings arepressed against the outer surfaces of the corner laps and firmlysecured. The upstanding marginal portions 2 of the cover end wings arethen turned in and adhesively secured to inner end wall surfaces and thebox part is then complete as shown in Fig. 7.

The apertures b in the shell material are shown of considerable width inFig. 1, largely-for the sake of clearness of illustration and While, ofcourse, the apertures may be so made, resulting ill-the edges 26 of theshell end wings being located considerably inward from the sidewallsofthe box, these edges may otherwise be located much nearer tion methodasshown in Fig. 1,'the ape'r:

tures b will be made correspondingly narrow. Fig. 9 shows a completedbox part made from the bIankmf Fig. '8, showing that the marginalportions k of the-cover end wing material. extending beyond the shelledges 26 may. be quite narrow, and

ciently wide in fact, to provide for only su proper covering of theshell edges 26 and proper'adhesion to outer surfaces of the box endwall. Figs. 8 and 9 also illustrate'an arrangement in which the cornerlaps 23 are relatively'short so that their inner ends do notapproximately meet, but aria in fact, 1 'widely separated in thecompleted box part,

as shown in Fig. 9.

In some'cases the'end end wings may be diiferently arranged orproportioned. For instance, in Fig. 10 these edges 40 are cutdiagonally. When such a blank is .folded into box form, as shown in Fi12,-the shell edges 40 while fully concea ed by the cover paperproducean ap-. 'preciable irregularity or shoulder onthe edges of the shell vexterior surface of the box end "and in this way produce an appearanceresembling that of one typical form of loose-wrapped box. Insome casesthe cover material adjacent to, the diagonal shell edge 40, forinstance, at

45, Fig. 11, may be cut approximately parallel to the shell edge, thatis on a diagonal line, leaving, however, a marginal portion .46 of thecover material, sufiicient to overlap and cover the shell edge in thecompleted box, Fig. 13, and also of sufficient Width to properly adheretothe outer sur-- face of'the adjacent corner lap. Thisarrangement'produces a box still more closely resembling a ty icalloose-wrapped box. o' By thedescn ed methods and principles ofconstruction all portions,including the edges of the shell end wings,are fully covered and concealedby overlying portions. of the covermaterial and the box part corre sponds to the highest requirements ofthe folding mechanism, with adhesive applied where necessary, to makethe completed box parts; or, of course, the folding and securing of theblanks into box formmay be done by hand operations where machines arenot available.

As sufliciently explained in my prior patents and pending'applications,the formation of the central openings w in the shell web is in onerespect required only for boxes of certain dimensions. Where thedimensions vary so that the end wings and esspecially the shell portionsof the endwings are only as long as the corner laps, the formation ofthese openings w may be omitted; and in that case the shell end wing andcorner la formations will be sufficiently duced y forming thelongitudinal openings 6. The severing cuts along the lines 15 will thensever the corner laps and the shell end wings at the same time. Onaccount ofother dimensional variations, the length of the openings w mayalso be varied'as desired.

The broader aspects of the production of the cover margins or flaps kalongside the longitudinal end wing edges 26, as herein disclosed, areclaimed in the present application; but the production of such covermargins or flaps in certain other aspects or more limited aspects, anddifferent variation s of the present method and structure,

are disclosed and claimed in my companion applications Ser. No.,612,170,filed January 12, 1923, and Ser. No. 612,171, filed-January 12, .1923. iWhat I claim is g V 1.
